Upper Wetzikon
Fig. 9: The district in upper Wetzikon where my parents and my sister lived. My mother didn't know that we were in a hot air balloon. I called her on the mobile phone and told her to step out and look for a hot air ballon. If you see a white dot on a terrace, that's her waving a blanket. — Minolta XD-7, 26 October 2003
